I am all for that!! Brilliant idea- and would be really funny to watch the pompous President of Mexico deal with them- I'm sure firing squads would regain popularity south of the border.
It's important to focus our anger where it belongs. We should not be angry at the illegals. Rather, the fault lies squarely on the shoulders of the American politicians who, to all intents and purposes have been, for decades, telling the illegals, "Come on over. There are good jobs and houses. Sure, it's illegal but we're going to make it as easy on you as we can. You pretend to be legal and we'll pretend to enforce the borders. Oh, and just ignore the yahoos who want border security. We don't listen to them anyway."
The McCains, Kennedys, Grahams, Clintons and Bushes have all actively created an enormous mess. When someone tries to repair the damage, they call us rascist.
